Server part of autotestnet net edition (since 2.0)

Description

This project is used for server side of autotestnet (start from version 2.0) net edition.
From v2.0, autotestnet use http to contact server(mysql) for all data storage, and a public service site was launched in pythonanywhere to support this. Before that, it contact mysql server directly by mysqltcl which need user to maintain mysql server by themselves, and, install mysqltcl is also a pain sometimes.
